2600k PPD = two of my rigs combined. Ouch.

[Sparky]

Did some rough number crunching. An overclocked 2600k does 45-50k PPD (correct me if I'm wrong). My Arima AND my 955BE combined do about that. OK, well, the 2600k is a few years newer after all. But then, the power consumption numbers... ouch. Between the two rigs I'm using at least 750 watts from the wall. A 2600k box uses what, 300 watts?

Now I'm thinking I should have jumped on that sick Microcenter board + CPU deal they had going on - the one that was stackable with the extra $50 off facebook coupon - and then sold my Arima and my 955BE setup. I could have at least broken even on that I would think! Assuming I could find a buyer for my Arima, it is a rather specialized rig really.

I guess I wasn't too smart.

Oh, and as a side note, while my i7 does pretty good at crunching (even at stock speeds, I can't overclock it unless I lap the thing, concave IHS), I really don't like it for day to day usage. Maybe it is because it is crunching, I don't know, but it is not a very refined system. The numbers don't lie, it performs very well, but the experience with it is, well, very stuttery and jarring. My 955 while slower is, ah, "smoother" by far (don't smack me! ).

Maybe I should look at selling some stuff here soon and keeping my eyes open for another microcenter combo deal...

The 2600K has changed the game. Simple as that. I replaced everything I had with three of them and now I'm doing more points/work at half the power usage and a much cooler and quieter room. Time to sell your stuff if you're serious about crunching

[Otis11]

The scary part is I think your numbers are a bit high on the 2600k power usage. Ran through 20 pages of WCG history since with the server update I can't look through my posts... but no luck. IIRC, my 2600k at stock with 2 x GTX 260s idle was 210W CPU loaded, OCed to 4.6 was 270W CPU Loaded GPUs idle - so guessing 30W each for idle GPUs (???) that's 210W 4.6 fully loaded - again IIRC.

[Sparky]

I realize for the same power usage I could be doing so much more, at the same time I don't want to spend any extra money up front to do so (I have something big I've been saving my pennies for for the last couple of months now).

If I could sell my Arima now, I would. Heck, I'd sell both my rigs now. Maybe even the i7 I have at the office (I own it, work doesn't) though while I kind of dislike how it runs it would be the last of the 3 I'd sell. But then, would the 2600k run like the 950 does, choppy-like? That would drive me totally bats.

My power numbers was for the total system draw from the wall. And yeah, I kinda pulled it out of thin air

[shoota]

First off yeah 300W for SB is way too much. Second, my i7-950 rig was never "choppy". In fact I don't recall ever even owning a rig that was choppy so I don't know how to respond to that

[retro77]

Ya your old i7-950 is not choppy

For your main, you could set it to use 7 threads. At least with Lynnfield, Hyperthreading added about 33% PPD. Disable one thread and one core becomes (mostly) dedicated to crunching but it also starts juggling your other work.

Anyways, at least with the i7-950 here, I only noticed WCG's resource usage when I'm playing games. That's the only time it's choppy.

[Sparky]

Maybe there is something else going on with my 950 then, I don't know. The CPU does need a good lapping to get it flat. It is so concave it isn't funny. I can't even overclock the thing even slightly, the temps go nuts.

So.. anyone wanna buy my Arima or my 955BE?

[Movieman]

Sparky, my 2600k on an old "pre fix" Intel board with a bios from Nov 2010 because I can't get it to update, running at 4332 makes app 40K a day drawing 195w from the wall.

[Sparky]

In other words, I could be doing 160k PPD at my current electric usage at home that is only getting me 50k. Nice Too bad that would cost too much up front!

[shoota]

Just start small. Start by selling your extra rigs and piece together a new rig as you find good deals. I'm sure it won't cost that much to get up and running.

[Sparky]

I feel like I have asked this before, but what does a 2500k do compared to a 2600k PPD-wise? I know it has 4 fewer threads, but that is because of a lack of HT, so I'm not sure how much that makes a difference. I'm thinking of maybe getting a 2600k for my main rig and a 2500k for the office rig, and sell my i7 950, my AMD 955BE, and my Arima (along with some other random hardware I have lying around).

[shoota]

Subtracting 33% gives approximately 30k. Not too shabby if it fits the initial budget.

[Bun-Bun]

This is why I'm currently building two dedicated 2600k crunchers

And i agree first gen i7's feel choppy to me and their numbers don't impress me. I don't like em at all.

drawing 195w from the wall.

Mine draws less than that... but that's because it's in storage in the guest room along with my other systems (save my laptop).

And for comparison's sake, my i7-950 (133*24):



It's been crunching HCMD up until today; I've run out of work and it's just doing the occasional CEP2. The i7-920 is working through its own HCMD queue.

[kjeldoran]

The microcenter ad I received in the mail has the $50 off mobo+2600k combo. it is good until march.

My 920 isn't doing anywhere near those numbers. It can't even clear 20k PPD!

At what speed? Something is wrong because my 950 at stock 3.06GHz (I thought it was 3.2GHz? nvm) is putting down mid-upper 20s average easy, and has gone north of 30k PPD on occasion.

[Bun-Bun]

Stock. 2.66GHz. The thing runs so darn hot though! 60°C with a Zalman CNPS10X!

EDIT: Just remembered I forgot to start my 2600K crunching again after gaming last night! /facepalm I suck at this

[Sparky]

Sounds like yours might be like my 950 - badly concave. You may need to lap yours too.

[Bobsama]

Here's my i7-920 (133*21).



First-gen Core i7's can produce respectable numbers.

You can automaticly suspend boinc while gaming and have it resume when you stop playing.

So it just suspends while said exe's listed in the file are in memory? cool! Thanks!
